Sorry to double post, but does anybody know if the error is with the dog model, or the gear model? We plan to use a vex pro dog with a custom dog gear, and we aren't sure what the actual pattern is.

If the side surface of the dog pocket (where the torque is transmitted) is extended, it goes through the center of the gear. On the dog, this is not the case, and the side of the dog doesn't lie on a diameter. When they hit each other in the CAD model, they only contact along one edge.
